Abstract

A device for forming a seal-rupture part in a package and a pressure-sensitive adhesive tape for seal-rupture are provided with which it is possible to easily and reliably form a seal-rupture part in a resin-film package without damaging the contents. The device for forming a seal-rupture part in a package is provided with: a cutting blade with which a strip of a pressure-sensitive adhesive tape to be applied to the package is cut out of a rolled pressure-sensitive adhesive tape for seal-rupture; an application jig with which the pressure-sensitive adhesive tape strip that has been cut out is applied to the resin film; and an incision jig with which an incision is formed in the resin film. The pressure-sensitive adhesive tape is equipped with a plurality of tabs disposed apart from one another in the lengthwise direction. The pressure-sensitive adhesive tape is drawn out with the application jig and cut into a desired length with the cutting blade. Thereafter, some of the cut strip of the pressure-sensitive adhesive tape is applied with the application jig. Due to the pulling stress applied to the pressure-sensitive adhesive tape, the resin film is pulled apart from the contents. An incision is formed in this pulled-apart portion with the incision jig. The entire surface of the strip of the pressure-sensitive adhesive tape is applied so as to cover the incision.

Description

包装体の開封部形成装置及び開封用粘着テープOpening part forming device for packaging body and adhesive tape for opening
　本発明は、包装体に開封部を形成するための装置及びこの装置で用いる開封用粘着テープに関する。より詳しくは、被包装体が樹脂フィルムで被包された包装体の開封性向上技術に関する。 The present invention relates to an apparatus for forming an opening portion in a package and an adhesive tape for opening used in this apparatus. More specifically, the present invention relates to a technique for improving the openability of a package body in which the package body is encapsulated with a resin film.
　シュリンク包装などの樹脂フィルムを使用した包装方法は、簡便な方法で商品を密封することができ、かつ開封の有無を容易に確認することができるため、食品や店舗に陳列される商品などで広く利用されている。このような包装に使用される樹脂フィルムには、ポリ塩化ビニル樹脂、ポリエチレン樹脂及びポリプロピレン樹脂などの機械的強度に優れ、破れにくい材料が使用されている。この包装用樹脂フィルムにおける破れにくいという特徴は、包装時の作業性及び包装後の取扱性の面では長所となるが、その一方で、包装体が開封しにくいという短所にもなる。 Packaging methods using resin films such as shrink wrapping can be used to seal products in a simple manner and easily check whether or not they are opened. It's being used. For the resin film used for such packaging, materials having excellent mechanical strength such as polyvinyl chloride resin, polyethylene resin, and polypropylene resin, which are not easily torn are used. The characteristic that the resin film for packaging is hardly torn is an advantage in terms of workability during packaging and handling after packaging, but also has a disadvantage that the package is difficult to open.
　このような包装体の開封を容易にするための方法としては、例えば、包装用樹脂フィルムの内側に開封用の帯体を設ける方法、包装体の端部に切り欠きを設ける方法、包装用樹脂フィルムにミシン目を入れる方法、包装用樹脂フィルムに開封用の切り込みを形成する方法（例えば、特許文献１参照。）などがある。しかしながら、例えば、シュリンク包装などのように商品を被包した後でフィルムを熱収縮させる包装方法の場合、特許文献１に記載の技術のように、予めフィルムに加工を施しておくと、開封部の形状が変形したり、位置が変動したりすることがある。また、樹脂フィルムによる包装は、包装材である樹脂フィルムと商品とが密着又は近接しているため、包装後の樹脂フィルムに加工を施すと、商品に疵をつける虞がある。 Examples of a method for facilitating the opening of such a package include, for example, a method of providing a band for opening inside a resin film for packaging, a method of providing a notch at the end of the package, and a resin for packaging There are a method of perforating the film, a method of forming an opening cut in the packaging resin film (for example, see Patent Document 1), and the like. However, for example, in the case of a packaging method in which a film is thermally shrunk after a product is encapsulated, such as shrink wrapping, if the film is processed in advance as in the technique described in Patent Document 1, the opening portion May be deformed or its position may be changed. Moreover, since the resin film which is a packaging material and the product are in close contact with or close to each other, the product may be wrinkled if the resin film after packaging is processed.
　一方、本発明者は、突片部を備える開封用粘着テープを用いた新たな形態の開封部を提案している（特許文献２，３参照）。特許文献２，３に記載の技術を用いることにより、被包装体に疵をつけることなく、樹脂フィルム包装体に、容易にかつ確実に包装体を開封することが可能な開封部を形成することが可能となる。また、従来、開封補助ラベルをその中央部より粘着面と非粘着面に二分し、非粘着面を把持用の耳部として構成し、粘着面をシュリンク包装体の破断誘導部と開封用帯の開封口に重ねて貼る形態も提案されている（特許文献４参照）。 On the other hand, the present inventor has proposed a new type of opening using an opening adhesive tape provided with a protruding piece (see Patent Documents 2 and 3). By using the techniques described in Patent Documents 2 and 3, an opening portion that can easily and reliably open the packaging body is formed on the resin film packaging body without causing wrinkles on the package body. Is possible. Further, conventionally, the opening assisting label is divided into an adhesive surface and a non-adhesive surface from the center portion, and the non-adhesive surface is configured as a gripping ear portion, and the adhesive surface of the shrink wrapping breakage portion and the opening band is formed. There has also been proposed a form of overlapping and pasting on the opening (see Patent Document 4).

　しかしながら、特許文献４に記載の技術のように、包装用樹脂フィルムの内側に開封用の帯体を設ける方法は、包装材のコストが大幅に増加するという問題点がある。また、包装前の樹脂フィルムに、開封用の切り欠き、ミシン目又は切り込みを形成する方法は、前述した理由から、シュリンク包装には不向きであり、包装後の樹脂フィルムにこのような加工を施すと、商品を疵つける虞があるという問題点がある。 However, as in the technique described in Patent Document 4, the method of providing an opening band inside the packaging resin film has a problem that the cost of the packaging material is significantly increased. In addition, the method of forming notches, perforations, or cuts for opening on the resin film before packaging is unsuitable for shrink wrapping because of the reasons described above, and such processing is performed on the resin film after packaging. There is a problem that there is a risk of finding the product.
　一方、樹脂フィルムを吸引しながら、熱盤やカッターによって、包装後の樹脂フィルムに開封部を形成する方法は、商品の破損は防止することができるが、樹脂フィルムに微小な穴が開いた瞬間に吸引が解除されるため、開封用として充分な大きさの切り込みを安定して形成することができないという問題点がある。また、この方法では、樹脂フィルムに吸引によるしわや疵が生じやすく、美観を損ねる虞もある。 On the other hand, the method of forming the opening on the resin film after packaging with a hot plate or cutter while sucking the resin film can prevent the product from being damaged, but at the moment when a minute hole is opened in the resin film Therefore, there is a problem that it is impossible to stably form a notch sufficiently large for opening. Moreover, in this method, wrinkles and wrinkles are easily generated in the resin film, which may impair the aesthetic appearance.
　これに対して、特許文献２，３に記載の技術は、被包装体を疵つけることなく開封部を形成することができるが、被包装体の種類によっては開封部が形成しにくかったり、開封しにくいことがあり、開封部の形成方法及び包装体の開封性について、更なる向上が求められている。 On the other hand, the techniques described in Patent Documents 2 and 3 can form an opening part without scratching the packaged body, but depending on the type of packaged body, the opening part is difficult to form or the package is opened. Further improvement is required for the method of forming the opening and the opening of the package.
　そこで、本発明は、被包装体を疵つけることなく、容易にかつ確実に、樹脂フィルムを使用した包装体に開封部を形成することができる包装体の開封部形成装置及び開封用粘着テープを提供することを主目的とする。 Therefore, the present invention provides an unsealed part forming apparatus and an unsealing adhesive tape for a package, which can easily and reliably form an unsealed part on a package using a resin film without scratching the packaged body.

（粘着テープ保持具２４）
　粘着テープ保持具２４は、ロール状の開封用粘着テープ３０を回転可能に保持するものであり、例えばロール状の開封用粘着テープ３０が装着された状態で、粘着装置から取り外し可能となっていることが好ましい。このようなカートリッジ形態を採用することにより、粘着テープロールを容易にかつ短時間で交換することができる。[Correction 25.08.2014 under Rule 91]
(Adhesive tape holder 24)

For example, the pressure-sensitive adhesive tape holder 24 can be detached from the pressure-sensitive adhesive device with the roll-shaped pressure-sensitive adhesive tape 30 for opening. It is preferable. By adopting such a cartridge form, the adhesive tape roll can be easily replaced in a short time.
（押圧部材２５）
　押圧部材２５は、樹脂フィルム２に対して粘着テープ３を確実に貼付するためのものである。押圧部材２５は、載置部１０の開口部１１の近傍に設置されていてもよいが、図１に示すように貼付治具２２と一体化された構成とすることもできる。 (Pressing member 25)
The pressing member 25 is for reliably sticking the adhesive tape 3 to the resin film 2. The pressing member 25 may be installed in the vicinity of the opening portion 11 of the mounting portion 10, but may be configured to be integrated with the sticking jig 22 as shown in FIG. 1.
［動作］
　次に、本実施形態の開封部形成装置１の動作、即ち、本実施形態の開封部形成装置を用いて樹脂フィルム包装体に開封部を形成するについて説明する。図５～図１０は開封部を形成する際の開封部形成機構の動作を示す図である。図１１は本実施形態の開封部形成装置１で用いる粘着テープの一例を示す斜視図である。なお、図５～図１１では、図を見やすくするために、切断刃２１、貼付治具２２、切り込み形成治具２３以外の構成要素は省略して示している。 [Operation]
Next, operation | movement of the opening part formation apparatus 1 of this embodiment, ie, forming an opening part in a resin film package using the opening part formation apparatus of this embodiment, is demonstrated. 5 to 10 are diagrams showing the operation of the opening portion forming mechanism when forming the opening portion. FIG. 11 is a perspective view showing an example of an adhesive tape used in the unsealed portion forming apparatus 1 of the present embodiment. 5 to 11, the components other than the cutting blade 21, the sticking jig 22, and the notch forming jig 23 are omitted for easy understanding of the drawings.
[規則91に基づく訂正 25.08.2014]　
　開封部形成装置１により、樹脂フィルム包装体５に開封部を形成する場合は、先ず、図１１に示す粘着テープ３０が保持されている粘着テープ保持具２４を取り付ける。そして、図５に示すように、貼付治具２２により粘着テープ３０の始端を把持し、所定長さ引き出した状態で停止する。この粘着テープ３０が貼付治具２２により引き出された状態を初期状態とする。なお、粘着テープ３０の引き出し長さは、形成予定の開封部の大きさなどに応じて適宜設定することができるが、粘着テープ３０に形成された突片部３ａが１個以上含まれる長さにする必要がある。[Correction 25.08.2014 under Rule 91]
When the opening part is formed on the resin film package 5 by the opening part forming apparatus 1, first, the adhesive tape holder 24 holding the adhesive tape 30 shown in FIG. 11 is attached. Then, as shown in FIG. 5, the start end of the adhesive tape 30 is gripped by the sticking jig 22 and stopped in a state where it is pulled out by a predetermined length. The state where the adhesive tape 30 is pulled out by the sticking jig 22 is defined as an initial state. The pull-out length of the adhesive tape 30 can be appropriately set according to the size of the opening portion to be formed, etc., but is a length that includes one or more protruding piece portions 3a formed on the adhesive tape 30. It is necessary to.
　次に、図６に示すように、載置部１０の所定位置に、開封部形成対象の樹脂フィルム包装体５を配置する。その方法は特に限定されず、コンベヤーやアームなどにより自動配置してもよく、また、作業者が手作業で配置してもよい。ここでいう樹脂フィルム包装体５は、商品などの被包装体４を、包装用樹脂フィルム２で被包したものであり、被包装体（商品）の形状、包装形態及び包装条件などについては、特に限定されるものではない。 Next, as shown in FIG. 6, the resin film package 5 to be opened is formed at a predetermined position of the placement unit 10. The method is not particularly limited and may be automatically arranged by a conveyor or an arm, or may be manually arranged by an operator. The resin film package 5 referred to here is a package 4 such as a product, which is encapsulated with the resin film 2 for packaging. For the shape of the package (product), the packaging form and the packaging conditions, It is not particularly limited.
　包装方法も特に限定されるものではないが、例えば、上包機による包装（キャラメル包装）や、フィルムの一部又は全部に熱処理を施すシュリンク包装などが挙げられる。また、樹脂フィルム包装体に使用する樹脂フィルムの材質は、特に限定されるものではないが、例えばシュリンク包装体の場合は、ポリエチレン樹脂、ポリプロピレン樹脂及びその他のポリオレフィン樹脂、ポリ塩化ビニル樹脂、ポリエチレンテレフタレート樹脂などの各種熱収縮性樹脂フィルムを使用することができる。 The packaging method is not particularly limited, and examples thereof include packaging with an overwrapping machine (caramel packaging) and shrink packaging in which a part or all of the film is heat-treated. The material of the resin film used for the resin film package is not particularly limited. For example, in the case of a shrink package, polyethylene resin, polypropylene resin and other polyolefin resins, polyvinyl chloride resin, polyethylene terephthalate. Various heat-shrinkable resin films such as resins can be used.
　そして、包装体検知部１２より樹脂フィルム包装体５が所定位置にあることが確認されると、図７に示すように、切断刃２１が突出して粘着テープ３を切断する。粘着テープ３０を切断した後、切断刃２１はスタンバイ位置に戻る。 Then, when it is confirmed by the package detection unit 12 that the resin film package 5 is in a predetermined position, the cutting blade 21 protrudes and cuts the adhesive tape 3 as shown in FIG. After cutting the adhesive tape 30, the cutting blade 21 returns to the standby position.
　次に、図８に示すように、切断された粘着テープ３を把持した状態で、貼付治具２２が回転し、載置部１０の開口部１１から露出している樹脂フィルム包装体５の包装材である樹脂フィルム２に、粘着テープ３の一部を貼付する。粘着テープ３の樹脂フィルム２への貼付量（面積）は、粘着テープ３に所定の引張応力を印加した際に、樹脂フィルム２から剥がれない程度であればよく、粘着テープ３と樹脂フィルム２との粘着強度などに応じて適宜設定することができる。 Next, as shown in FIG. 8, the packaging of the resin film package 5 that is exposed from the opening 11 of the mounting portion 10 is rotated while the adhesive tape 3 that has been cut is gripped. A part of the adhesive tape 3 is affixed to the resin film 2 that is a material. The sticking amount (area) of the adhesive tape 3 to the resin film 2 may be such that the adhesive tape 3 is not peeled off from the resin film 2 when a predetermined tensile stress is applied to the adhesive tape 3. It can set suitably according to the adhesive strength of this.
　また、このとき、貼付治具２２により貼付された粘着テープ３を、ローラーなどの押圧部材２５で樹脂フィルム２に押しつけてならすことが望ましい。これにより、次の動作で、引張応力を印加したときに、粘着テープが樹脂フィルムから剥離してしまうことを防止することができる。このならし工程は、樹脂フィルム２に、粘着テープ３が貼着しにくい材質のフィルムを使用しているときに特に有効である。 Further, at this time, it is desirable to press the adhesive tape 3 affixed by the affixing jig 22 against the resin film 2 with a pressing member 25 such as a roller. Thereby, it is possible to prevent the adhesive tape from peeling from the resin film when a tensile stress is applied in the next operation. This leveling process is particularly effective when a film made of a material to which the adhesive tape 3 is difficult to stick is used for the resin film 2.
　その後、貼付治具２２が下方、即ち、樹脂フィルム包装体５から離れる方向に、２～４ｍｍ程度移動する。これにより、粘着テープ３に引張応力が印加され、それに伴い、樹脂フィルム２が被包装体４から引き離され、これらの間に隙間ができる。この隙間は、次の工程で使用する切り込み形成治具２３が被包装体４に接触しない程度であればよい。 Thereafter, the sticking jig 22 moves downward, that is, about 2 to 4 mm in a direction away from the resin film package 5. Thereby, a tensile stress is applied to the adhesive tape 3, and accordingly, the resin film 2 is separated from the package body 4, and a gap is formed between them. This gap may be such that the notch forming jig 23 used in the next step does not contact the packaged body 4.
　そして、図９に示すように、切り込み形成治具２３を、樹脂フィルム２の被包装体４から引き離されている（浮いている）部分に刺し、切り込みを形成する。図１２Ａ～Ｃは切り込みの形状例を示す平面図である。樹脂フィルム２に形成する切り込みの形状は、例えば、図１２Ａに示すＵ字状の切り込み２ａ、図１２Ｂに示すＶ字状の切り込み２ｂ、図１２Ｃに示す直線状の切り込み２ｃなどが挙げられるが、これらに限定されるものではなく、適宜選択することができる。また、樹脂フィルム２に、間隔をあけて複数の切り込みを形成してもよい。 And as shown in FIG. 9, the notch formation jig | tool 23 is stabbed in the part separated from the to-be-packaged body 4 of the resin film 2 (floating), and an incision is formed. 12A to 12C are plan views showing examples of cut shapes. Examples of the shape of the cut formed in the resin film 2 include a U-shaped cut 2a shown in FIG. 12A, a V-shaped cut 2b shown in FIG. 12B, and a linear cut 2c shown in FIG. 12C. It is not limited to these, It can select suitably. A plurality of cuts may be formed in the resin film 2 at intervals.
　このとき、１回の動作で所定の切り込みを形成することも可能であるが、２回に分けて形成することが好ましい。切り込みを２回に分けて形成する方法の場合は、例えば、切り込み形成治具２３で樹脂フィルム２に小さな切り込みを形成し、その後、この切り込みを切り込み形成治具２３で大きくする。具体的には、第１段階として、樹脂フィルム２に切り込み形成治具２３を僅かに刺し、その後、貼付治具２２を下方（包装体から離れる方向）に例えば４～６ｍｍ程度移動させると共に、切り込み形成治具２３を樹脂フィルム２に向かって４～６ｍｍ程度移動させる。これにより、切り込み形成治具２３を安定して刺すことができると共に、切り込み形成治具２３を刺した際に、粘着テープ３が樹脂フィルム２から剥離することを防止できる。 At this time, it is possible to form a predetermined cut by one operation, but it is preferable to form it by dividing it into two. In the case of the method of forming the cut in two steps, for example, a small cut is formed in the resin film 2 with the cut forming jig 23, and then this cut is enlarged with the cut forming jig 23. Specifically, as a first step, the notch forming jig 23 is slightly stabbed into the resin film 2, and then the sticking jig 22 is moved downward (in the direction away from the package), for example, by about 4 to 6 mm, and the notch is cut. The forming jig 23 is moved toward the resin film 2 by about 4 to 6 mm. Thereby, while being able to stab the notch formation jig | tool 23 stably, when the notch formation jig | tool 23 is stabbed, it can prevent that the adhesive tape 3 peels from the resin film 2. FIG.
　また、切り込み形成用治具２３として通り刃や平刃のカッターを使用している場合は、樹脂フィルム２に刺す際に、その角度を１０～３０°程度傾けることが好ましい。カッターを傾けずに、包装体に平行な状態でその樹脂フィルム２に刺すと、図１２Ｃに示すような直線状の切り込み２ｃが形成されるが、前述した範囲で傾けて刺すことにより、図１２Ａに示すＵ字状の切り込み２ａや図１２Ｂに示すＶ字状の切り込み２ｂを形成することができる。これらＵ字状及びＶ字状の切り込み２ａ，２ｂは、直線状の切り込み２ｃに比べて、開封時に樹脂フィルム２が裂けやすく、良好な開封性が得られる。 Further, when a through blade or a flat blade cutter is used as the incision forming jig 23, it is preferable to tilt the angle by about 10 to 30 ° when piercing the resin film 2. When the resin film 2 is stabbed in parallel with the packaging body without tilting the cutter, a linear notch 2c as shown in FIG. 12C is formed. A U-shaped cut 2a shown in FIG. 5 or a V-shaped cut 2b shown in FIG. 12B can be formed. These U-shaped and V-shaped cuts 2a and 2b are easy to tear the resin film 2 at the time of opening compared to the straight cuts 2c, and good openability is obtained.
　樹脂フィルムに所定形状の切り込みを形成した後、切り込み形成用治具２３及び貼付治具２２を、図８に示す位置に戻す。これにより、粘着テープ３への引張応力が解除される。その後、図１０に示すように、貼付治具２２を移動させ、最終的に粘着テープ端部の把持を解除することにより、粘着テープ３の全面を樹脂フィルム２に貼付し、切り込みが形成されている部分を粘着テープ３で覆う。粘着テープ３の貼付方向は、粘着テープ３を剥がしたときに、切り込みを起点として樹脂フィルムが裂け、包装体が開封される方向とする。 After forming the notch of a predetermined shape in the resin film, the notch forming jig 23 and the sticking jig 22 are returned to the positions shown in FIG. Thereby, the tensile stress to the adhesive tape 3 is released. After that, as shown in FIG. 10, the sticking jig 22 is moved, and finally the grip of the adhesive tape end is released, so that the entire surface of the adhesive tape 3 is stuck to the resin film 2 and the cut is formed. The covered part is covered with the adhesive tape 3. The adhesive tape 3 is attached in the direction in which, when the adhesive tape 3 is peeled off, the resin film is torn from the notch and the package is opened.
　また、このとき、必要に応じて、開口部１１近傍に配置された押圧部材などにより、全面貼付された粘着テープ３をならす。これにより、粘着テープ３を全面に亘って樹脂フィルム２に確実に貼付し、搬送又は取り扱い時に、粘着テープ３が剥がれて、包装体５が開封されてしまうことを防止することができる。 At this time, the adhesive tape 3 adhered to the entire surface is smoothed by a pressing member or the like disposed in the vicinity of the opening 11 as necessary. Thereby, the adhesive tape 3 is reliably affixed to the resin film 2 over the whole surface, and it can prevent that the adhesive tape 3 peels off at the time of conveyance or handling, and the package 5 is opened.
　図１３は本実施形態の開封部形成方法で形成した開封部を備える包装体の一例を示す斜視図であり、図１４Ａ，Ｂはそれぞれ図１２Ｂ，Ｃに示す切り込み２ｂ，２ｃを備える開封部を模式的に示す平面図である。前述した動作により、図１３に示すように、樹脂フィルム包装体１０に、被包装体４を覆う樹脂フィルム２に設けられた切り込みと、開封用粘着テープ３とからなる開封部が形成される。この開封部は、例えば、図１４Ａ，Ｂに示すように、突片部（摘み部）３ａを持って粘着テープ３を剥がすことにより、容易にかつ且つ確実に、樹脂フィルム包装体５を開封し、被包装体４を取り出すことができる。 FIG. 13 is a perspective view showing an example of a package including an opening portion formed by the opening portion forming method of the present embodiment, and FIGS. 14A and 14B show opening portions provided with cuts 2b and 2c shown in FIGS. 12B and 12C, respectively. It is a top view shown typically. By the above-described operation, as shown in FIG. 13, an opening portion formed by the notch provided in the resin film 2 covering the package body 4 and the opening adhesive tape 3 is formed in the resin film package 10. For example, as shown in FIGS. 14A and 14B, the unsealing part can easily and surely unseal the resin film package 5 by peeling off the adhesive tape 3 with a protruding piece part (pick part) 3a. The packaged body 4 can be taken out.
　その後、切り込み形成用治具２３は、図５に示す位置に戻り、粘着テープ３の始端を把持し、所定長さ引き出した状態で停止する。一方、開封部が形成された樹脂フィルム包装体５は、自動又は作業者により、載置部１０から移動される。 After that, the notch forming jig 23 returns to the position shown in FIG. 5, holds the starting end of the adhesive tape 3, and stops in a state where it is pulled out by a predetermined length. On the other hand, the resin film package 5 in which the opening portion is formed is moved from the placement portion 10 automatically or by an operator.
　以上詳述したように、本実施形態の開封部形成装置では、樹脂フィルムに貼付する前に、開封用粘着テープを一定長さに切断しているため、樹脂フィルムに貼付する際の作業性が向上し、開封部を安定して形成することができる。また、本実施形態の開封部形成装置は、切断した粘着テープの一部を樹脂フィルムに貼付し、この粘着テープに引張応力を印加することにより、樹脂フィルムを被包装体から離しているため、樹脂フィルムなどの包装材を吸引するための設備が不要となる。 As described above in detail, in the opening part forming apparatus of the present embodiment, the adhesive tape for opening is cut to a certain length before being attached to the resin film, so that workability when attaching to the resin film is improved. The opening part can be formed stably. Moreover, since the opening part formation apparatus of this embodiment is separating the resin film from the package body by applying a tensile stress to the adhesive film by applying a part of the cut adhesive tape to the resin film, Equipment for sucking packaging materials such as resin films is not required.
　本実施形態の開封部形成装置では、カッターなどの切り込み形成治具により樹脂フィルムに切り込みを形成しているため、熱源が不要であり、被包装体が熱で変形する虞もない。その結果、装置を簡略化及び小型化することができると共に、被包装体に疵をつけることなく、樹脂フィルム包装体に開封部を形成することができる。また、本実施形態の開封部形成装置は、摘み部となる突片部を備える開封用粘着テープを用いているため、容易にかつ確実に包装体を開封することが可能な開封部を形成することが可能である。 In the unsealing part forming apparatus of this embodiment, since the cut is formed in the resin film by a cutting forming jig such as a cutter, a heat source is unnecessary, and there is no possibility that the packaged body is deformed by heat. As a result, the apparatus can be simplified and miniaturized, and the opening portion can be formed in the resin film package without wrinkling the package. Moreover, since the opening part formation apparatus of this embodiment uses the adhesive tape for opening provided with the protrusion part part used as a pick part, it forms the opening part which can open a package body easily and reliably. It is possible.
　更に、本実施形態の開封部形成装置では、包装体を載置する位置を任意に設定することが可能であるため、開封部の位置を個別に変更することが可能となると共に、大きさ及び形状にかかわらず、樹脂フィルムを使用した種々の包装体に開封部を形成することができる。特に、樹脂フィルムとして破れにくい熱収縮性フィルムを使用しており、被包装体と包装材とが密着していることが多く、端部に開封部を形成しにくいシュリンク包装体に好適である。 Furthermore, in the opening part formation apparatus of this embodiment, since it is possible to arbitrarily set the position where the package is placed, the position of the opening part can be individually changed, and the size and Regardless of the shape, the opening portion can be formed on various packaging bodies using a resin film. In particular, a heat-shrinkable film that is not easily torn is used as the resin film, and the packaged body and the packaging material are often in close contact with each other, which is suitable for a shrink package that hardly forms an opening at the end.
